Mean (standard deviation) of the bond strengths (MPa) of different brackets

Bond strength test mode	Type of bracket
	Stainless steel	Ceramic	Titanium
Shear strength short side	15.12 (2.34) a A	21.76 (3.43) a B	10.21 (2.10) a C
Shear strength long side	12.15 (2.03) b A	15.25 (2.88) b B	7.69 (1.17) b C
Tensile strength	8.05 (1.24) c A	12.05 (2.26) c B	5.07 (1.11) c C

Mean values represented with common or same uppercase letters (row) are not significantly different according to Tukey's test (P > 0.05). Mean values represented with common or same lowercase letters (column) are not significantly different according to Tukey's test (P > 0.05).
